Now that the outstanding writes are counted in bytes, there is no need
to use the low-level __bio_try_merge_page API, we can switch back to
always using bio_add_page and simply iomap_add_to_ioend again.

These two callers were the only external users of __bio_try_merge_page(),
so it can now be made static to block/bio.c.

Yeah, but doing so in the same merge window will create an annoying
cross dependency.  I have a series to cleanup a whole lot of the
bio_add_page related code including starting to clean up the return
value for the next merge window.
